A "sun grazing" comet as caught by Solar and Heliospheric Observatory's (SOHO) Large Angle Spectrometric Coronagraph (LASCO) C2 camera as it dived toward the sun on July 5 and July 6. SOHO is the overwhelming leader in spotting sungrazers, with over 2000 spotted to date, aided by the fact that the sun's bright light is itself blocked out by the coronograph. The SOHO LASCO C2 camera images the inner solar corona up to 8.4 million kilometers (5.25 million miles) away from the Sun....

In early December, the Solar and Heliospheric Observatory's (SOHO) online "Pick of the Week" reached an impressive milestone: its 500th edition. This is an incredibly popular feature, which highlights one video or image of the sun each week. Featured here are solar images taken from November 22-28, 2011. The Sun produced about a dozen coronal mass ejections (CMEs) in eight days and it did seem like it was working overtime. The SOHO C2 coronagraph shows the storms (both large and...

Still from video: Comet Lovejoy blazes toward the sun and its tail wiggles as it interacts with the solar wind. By the end of the day on December 15, 2011, the comet will graze some some 75,000 miles above the sun's surface through the several million degree solar corona, and quite likely evaporate. The movie was recorded by STEREO using the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instrument. Credit: NASA/STEREO/NRL › Link to associated news item

This image from the Solar Heliospheric Observatory (SOHO) taken the morning of Dec. 16, 2011 shows the comet head emerging from the right side of the sun. The comet does seem to have left its tail behind, however –that's the nearly vertical streak that remains on the left side of the sun. The comet's survival surprised NASA scientists.

Still from video: Comet Lovejoy blazes toward the sun and its tail wiggles as it interacts with the solar wind as seen by the Solar Dynamics Observatory (SDO), which adjusted its cameras in order to watch the trajectory. Not only does this help with comet research—such as how big the comet is and what it's made of -- but it may also help orient instruments on SDO. Since the scientists know where the comet is based on other spacecraft, they can finely determine the position of SDO's mirrors....

A cut-away illustration of Earth's interior. At the heart of our planet lies a solid iron ball, about as hot as the surface of the sun. Researchers call it "the inner core", which is 70% as wide as the moon. It spins at its own rate, as much as 0.2o of longitude per year faster than the Earth layers above it. Surrounding the iron ball is an ocean of liquid iron known as "the outer core." This inner and outer core duo is referred to as Earth's geodynamo. Surrounding the core...

By tracking how the comet interacts with the sun's atmosphere, the corona, and how material from the tail moves along the sun's magnetic field lines, solar scientists hope to learn more about the corona.

Schematic illustration of the invisible magnetic field lines generated by the Earth, represented as a dipole magnet field. In actuality, our magnetic shield is squeezed in closer to Earth on the Sun-facing side and extremely elongated on the night-side due to the solar wind. Earth's polarity is not a constant. Unlike a classic bar magnet, the matter governing Earth's magnetic field moves around. Geophysicists are pretty sure that the reason Earth has a magnetic field is because its solid iron...

The sun let loose with at least six coronal mass ejections (CMEs) -- solar phenomena that can send solar particles into space and affect electronic systems in satellites -- from 7 PM ET on September 18, 2011 until 1 PM on September 19. The ejections appear to come from points scattered over the surface of the sun. Two CME's dissipated quickly, but four continue to spread outward from the sun. NASA models suggest that the leading edge of one CME will pass by Earth at around 5 PM ET on Sep 21, at...

A sunspot prediction for solar cycle 24. Planning for satellite orbits and space missions often require knowledge of solar activity levels years in advance. Current prediction for the next sunspot cycle maximum gives a smoothed sunspot number maximum of about 58 in July of 2013. As of March 2011, we are over two years into Cycle 24. The predicted size would make this the smallest sunspot cycle in nearly 200 years. Credit: NASA/MSFC/Hathaway

A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun's surface. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona. A prominence forms over timescales of about a day, and stable prominences may persist in the corona for several months, looping hundreds of thousands of miles into space. Scientists are still researching how...

On January 4, the Hinode satellite captured these breathtaking images of an annular solar eclipse. An annular eclipse occurs when the moon, slightly more distant from Earth than on average, moves directly between Earth and the sun, thus appearing slightly smaller to observers' eyes; the effect is a bright ring, or annulus of sunlight, around the silhouette of the moon. Hinode, a Japanese mission in partnership with NASA, NAOJ, STFC, ESA, and NSC, currently in Earth orbit, is studying the Sun to...

A very long solar filament that had been snaking around the Sun erupted Dec. 6, 2010 with a flourish. NASA’s Solar Dynamics Observatory (SDO) caught the action in dramatic detail in extreme ultraviolet light of Helium. It had been almost a million km long ((about half a solar radius) and a prominent feature on the Sun visible over two weeks ago before it rotated out of view. Filaments are elongated clouds of cooler gases suspended above the Sun by magnetic forces. They are rather unstable and...

NASA's STEREO spacecraft watched as an eruptive prominence rose up and arched out in a horseshoe shape far above the Sun's surface (Aug. 25, 2010). The image shows the action in an extreme UV wavelength as an eruptive prominence churns, then rises up, arches out, and finally breaks apart and dissipates above the solar surface. Prominences are clouds of relatively cool gases suspended in the Sun's hot corona by magnetic fields that sometimes break loose to create these dramatic eruptions. This...

This Solar Dynamics Observatory image of the Sun taken on January 10 in extreme ultraviolet light captures a dark coronal hole just about at sun center. Coronal holes are areas of the Sun's surface that are the source of open magnetic field lines that head way out into space. They are also the source regions of the fast solar wind, which is characterized by a relatively steady speed of approximately 800 km/s (about 1.8 million mph).

A magnetosphere is that area of space, around a planet, that is controlled by the planet's magnetic field. The shape of the Earth's magnetosphere is the direct result of being blasted by solar wind. The solar wind compresses its sunward side to a distance of only 6 to 10 times the radius of the Earth. A supersonic shock wave is created sunward of Earth called the Bow Shock. Most of the solar wind particles are heated and slowed at the bow shock and detour around the Earth in the Magnetosheath....

The sun and its atmosphere consist of several zones or layers. From the inside out, the solar interior consists of the core, the radiative zone, and the convection zone. The solar atmosphere is made up of the photosphere, the chromosphere, a transition region, and the corona. Beyond the corona is the solar wind, which is actually an outward flow of coronal gas. The sun's magnetic fields rise through the convection zone and erupt through the photosphere into the chromosphere and corona. The...

This is an artist's concept of our Heliosphere as it travels through our galaxy with the major features labeled. Termination Shock: Blowing outward billions of kilometers from the Sun is the solar wind, a thin stream of electrically charged gas. This wind travels at an average speed ranging from 300 to 700 kilometers per second (700,000 - 1,500,000 miles per hour) until it reaches the termination shock. At this point, the speed of the solar wind drops abruptly as it begins to feel the effects...

Where do meteor showers originate? To help answer this question, astronomers studied his past weekend's Quadrantid meteor shower. In particular, astronomers with specialized cameras flew as part of the Quadrantid's Multi-Instrument Aircraft Campaign (MAC) aboard a NASA DC-8 aircraft above northern Canada and studied the meteor shower in unprecedented detail. Pictured above is a composite image combining many short exposures. Visible in the image are the tail of the airplane reflecting a red...

The South Pole-Aitken Basin is a prominent lunar feature in many respects. In addition to being the principal shaper of topography (top right) of the farside of the Moon, the basin floor is the primary compositional anomaly of the farside and the highlands of the Moon. The albedo map (top left) shows that the floor of the basin is markedly darker than the highlands surrounding it. Both iron (bottom left) and titanium (bottom right) concentration maps show enhanced values associated with the...

Sunset on Mars catches NASA's proposed Mars Science Laboratory in the foreground in this artist's concept. The mission is under development for launch in 2009 and a precision landing on Mars in 2010. Once on the ground, the Mars Science Laboratory would analyze dozens of samples scooped up from the soil and cored from rocks as it explores with greater range than any previous Mars rover. It would investigate the past or present ability of Mars to support life. NASA is considering nuclear energy...

This sprawling look at the martian landscape surrounding the Mars Exploration Rover Spirit is the first 3-D stereo image from the rover's navigation camera. A surface depression nicknamed "Sleepy Hollow" can be seen to center left of the image. Scientists theorize that this topographic feature, measuring about 10 meters (30 feet) in diameter and located approximately 10 to 20 meters (30 to 60 feet) away from Spirit, is either an impact crater or a product of wind-erosion.

The artist's rendition shows the newly discovered planet-like object, dubbed 'Sedna,' in relation to other bodies in the Solar System, including Earth and its Moon; Pluto; and Quaoar, a planetoid beyond Pluto that was until now the largest known object beyond Pluto. The diameter of Sedna is slightly smaller than Pluto's but likely somewhat larger than Quaoar. *Image Credit*: NASA/JPL-Caltech/R. Hurt (SSC-Caltech)

On January 3, Spirit, NASA's 400-pound rover, is scheduled to land on what may be a dried-up lake bed on Mars. "There's not much doubt: this site contained a body of liquid water, at least for some amount of time," says Jim Garvin, NASA's Lead Scientist for Mars Exploration. The site is Gusev Crater, a 90-mile wide hole in the ground that probably formed three to four billion years ago when an asteroid crashed just south of Mars' equator. There's a channel system that drains into it,...

The interior of a crater surrounding the Mars Exploration Rover Opportunity at Meridiani Planum on Mars can be seen in this color image from the rover's panoramic camera. This is the darkest landing site ever visited by a spacecraft on Mars. The rim of the crater is approximately 10 meters (32 feet) from the rover. The crater is estimated to be 20 meters (65 feet) in diameter. Scientists are intrigued by the abundance of rock outcrops dispersed throughout the crater, as well as the crater's...

As Spirit descended onto Mars' surface on Jan. 3, 2004 it performed a series of entry, descent and landing actions, leaving visible marks on the surface of Mars. This "path" of Spirit's descent can be seen labeled in this image.

Ralph is a digital imager set to fly on NASA's New Horizons mission to Pluto and the Kuiper Belt. It must be able to take sharp images in sunlight levels 1,000 times fainter than what we see on Earth. Ralph consists of three panchromatic (black-and-white) and four color imagers inside its Multispectral Visible Imaging Component (MVIC), as well as an infrared compositional mapping spectrometer called the Linear Etalon Imaging Spectral Array (LEISA). Ralph's suite of seven detectors - all...

*Jupiter* Jupiter's composition is mainly hydrogen and helium. In contrast to planetary bodies covered with a hard surface crust (the Earth, for example), the jovian surface is gaseous-liquid, rendering the boundary between the atmosphere and the planet itself almost indistinguishable. Below the roughly 1000-kilometer-thick atmosphere, a layer of liquid hydrogen extends to a depth of 20,000 kilometers. Even deeper, it is believed that there is a layer of liquid metallic hydrogen at a pressure...

This diagram shows the relative size of the orbits of the seven planets visible to the naked eye. All the orbits are nearly circular (but slightly elliptical) and nearly in the same plane as Earth's orbit (called the ecliptic). The diagram is from a view out of the ecliptic plane and away from the perpendicular axis that goes through the Sun. *Image Credit*: Lunar and Planetary Institue
